I want a DOS head to engage the program I have it on when PH is greater than x.xx.
I want to bounce between Sodium Hydroxide and Sodium BiCarb. It’s easy on the Hydroxide pump (If PH > x.xx then off), that works well. But if I do the opposite for the other pump (if PH > x.xx then on) it turns the pump on nonstop, it doesn’t allow the pump to follow the programming. Does anyone have any ideas?
